Tried using some old wrought iron from a 1920s farm gate for a knife, the grain structure was a total surprise

Oh come on, are you kidding me? Old metal doesn't get "tired" or "remember" anything, that's not how science works. Steel is steel, it's a mix of iron and carbon with some trace elements, not a living thing with a memory. If it crumbles or flowers open, that's because you messed up the heat treatment or the steel was loaded with impurities from the start. People have been blaming bad work on "tired metal" for a hundred years as an excuse. Wrought iron from a farm gate probably had slag inclusions and inconsistent carbon distribution, which is totally normal for that era. You just gotta know how to handle it, not blame the metal for being old.

Remember my buddy tried that with an old wagon spring. He got it hot and the metal just kinda... flowered open like weird steel lace. Totally threw him off.

Yeah I used to think old steel was just tougher. But I saw something like that happen with a leaf spring from a truck. Heated it up and it just crumbled apart, like burnt paper almost. Made me realize that old metal gets tired, like it's been worked too hard. Changes how you pick your materials for sure.
